DeepResearchEval
Deep research systems answer complex research tasks that require evidence from many web sources. A persona-driven pipeline writes the tasks and keeps only those that need outside search. A model judge scores each report on general and task-specific dimensions, and an agent fact-checks the report's statements with web search even when citations are missing.
Version 1 has 100 expert-validated tasks. A version 2 task set came out in 2026-02. The pipeline can generate new tasks, so scores depend on the task release. Quality is a 0 to 10 score and factual accuracy is a separate percentage. 126 Hugging Face upvotes and about 142 GitHub stars.

In the authors’ words
Deep research systems are widely used for multi-step web research, analysis, and cross-source synthesis, yet their evaluation remains challenging. Existing benchmarks often require annotation-intensive task construction, rely on static evaluation dimensions, or fail to reliably verify facts when citations are missing. To bridge these gaps, we introduce DeepResearchEval, an automated framework for deep research task construction and agentic evaluation. For task construction, we propose a persona-driven pipeline generating realistic, complex research tasks anchored in diverse user profiles, applying a two-stage filter Task Qualification and Search Necessity to retain only tasks requiring multi-source evidence integration and external retrieval. For evaluation, we propose an agentic pipeline with two components: an Adaptive Point-wise Quality Evaluation that dynamically derives task-specific evaluation dimensions, criteria, and weights conditioned on each generated task, and an Active Fact-Checking that autonomously extracts and verifies report statements via web search, even when citations are missing.
Gemini-3 DR research agent tops the leaderboard with 8.05
Best score per entry from the benchmark's own leaderboard, read on November 12th, 2026. Where a model ran with several settings or harnesses, we keep its best. Names in gray aren't in our model list: fine-tunes, agent systems, products and older models. They don't count toward leaders.
